3 Power Plant Development :

1. Patuha 1x55 MW, which is scheduled to start commercial operation in 2014, (Geodipa, 2014)

Patuha Power Plant Construction 20/05/2014



3 Power Plant Development :

2. Sarulla 330 MW (World’s largest geothermal plant), where the 1st phase (3x60 MW) is scheduled to start operation in 2016. (Asian Developmen Bank, 2014, Medco 2014). 1stwell /drilling started 23 September 2014. The plan is to drill 34 production and injection wells. Development of infrastructure is in progress.

3. Lumut Balai unit 1, 55 MW will be ready for commercial operation in 2015, while unit 2 is in progress and is expected to be ready for commercial operation in 2016 (PGE Annual Report 2012)



2 Steam Field Development :

Ulubelu unit 3 and 4, 2x55 MW and

1. Hot Sedimentary Aquifer for Geothermal Cooling

2. Binary Plant for medium enthalpy resources

3. Direct Use



Hot Sedimentary Aquifer Hot Sedimentary Aquifer for Geothermal Coolingfor Geothermal Cooling

LAPI ITBLAPI ITB‐‐IF Technology, 2014IF Technology, 2014

• Preliminary Study

• Initiated by Pertamina Corporate in 2014

• To provide cooling for skyscraper building with “zero

energy” in the heart of Jakarta

• The potential resources seems to be promising

• The major concern are the environmental and social

community



Binary Plant for Medium Enthalpy ResourcesBinary Plant for Medium Enthalpy Resources

• Current study are conducted in Lahendong and Wayang Windu, the study is carried out in collaboration with German Institutions

• Jailolo (Star Energy) are being studied.

• Other interest coming from Japanese Company to study the possibility of binary plant in some prospect located in West Java Province.

Personal Communications from various sources



Direct Use

• In the phase of Desk Study

• Geothermal low enthalpy for manufacturing facilities at Karawang City, a centre for industry

• Study of direct use for various purpose; milk sterilization, hotel cooling, etc.



Concluding Remark

• Indonesia is a country with large geothermal potential but the utilization, mostly for generating electricity with conventional plant, is still low.

• Exploitation of low to medium enthalpy is still in the phase of desk (literature) study

• There are still plenty opportunity for expanding geothermal energy utilisation
